The JRC Karlsruhe plans to purchase a criticality alarm system.

In rooms in which a critical mass of fissile nuclides cannot be ruled or in rooms where larger quantities of fissile material are handled, criticality measurement chambers shall be installed. These measure the gamma dose rate occurring in the event of a criticality and trigger a criticality alarm if a limit value is exceeded. The alarm is signalled visually and acoustically on site (also displayed before access to the monitored rooms) and transmitted

To the control room (optical and acoustic signalling).
